There isn't a link to download a .dmg file on the app store.
Apple enforces many constraints on apps in the app store, if everyone only uses that it won't be long before Apple removes the ability to install software directly and will have even more power over developers. I refuse to use it as I want to support developers ability to build apps they want to build and distribute without undue interference from Apple.
Here are many examples of why the app store is bad https://hn.algolia.com/?q=mac+app+store
Please can I have a link to a .dmg file so I can install it myself.
Free? That's irrelevant to to me as I'd be be a paying customer already if I could install the app without using the App Store. I can download an Andriod .apk, a windows .exe and for linux it's open source.
It's not about supporting Apple or not, I just don't want them to have too much leverage over developers or control over what I can run on my computer. I'll try the Apple Configuration Profile.
Apple actually removed the NextDNS app from the iOS app store about a month ago (validating my reasoning for not wanting to use the Mac App store). I don't know if the App Configuration Profile tool at apple.nextdns.io was built specifically as a workaround after the app was removed but I wouldn't be suprised. Maybe they knew it was always a possibility so built it as a contingency measure.
Seems odd to me that there's tool that will provide a signed configuration profile .mobileconfig yet I can't download a .dmg of the app, the app seems to be so much more user friendly. It's trivial to put it in an S3 bucket or similar.
